Successfully linstlled DNN9 using the excellent Chris Hammond Videos onto a windows 10 development environment.
Some weeks later returned to HTTP 500 error when trying to browse dnndev.me.
I therefore attempted a re-install but could not get the install package to initiate an install. SQL Express does not show any databases and NETWORK SERVICE and dnndev.me have access to the file system.
The log file shows a number of errors but these mean nothing to a novice like me.:-

Not sure what step has been missed but my guess is that in the interim I've installed some other product that has had this effect on DNN (.net 1.1?)
Hopefully someone has some ideas.
